Description

Technical Field

[0001] The invention relates to the technical field of tempered glass processing, in particular to a forming device and process for curved tempered glass. Background Art

[0002] Tempered glass bending is a process that heats the tempered glass to a point close to the softening point, then uses a mold or other auxiliary tools to bend it into the desired shape, and keeps the bent state after cooling; the original glass of the heat-bent tempered glass needs to have good heat-bending performance, and should avoid defects such as cracks, bubbles, and inclusions. The bent tempered glass needs to be cooled quickly to fix its shape;

[0003] Before the tempered glass is hot-pressed, the edges of the bent tempered glass are thinner and have a larger area in contact with the outside world, which makes it cool down quickly. Therefore, it is easily affected by thermal stress and cracked during hot bending. At the same time, in the process of rapid cooling of the bent tempered glass, directly spraying water for cooling will cause the temperature change to be too drastic, and the moisture remaining on the surface of the tempered glass is unevenly distributed, which can easily lead to uneven shrinkage of the tempered glass and affect the product quality of the curved tempered glass. Summary of the invention

[0004] The technical problems solved by this solution are:

[0005] (1) How to solve the problem that direct water spraying for cooling causes excessive temperature changes and uneven distribution of moisture remaining on the surface of tempered glass, which easily leads to uneven shrinkage of tempered glass and affects the quality of curved tempered glass products;

[0006] (2) How to solve the problem that the edge of the heat-bent tempered glass is thinner and has a larger area in contact with the outside world, which causes it to cool down quickly and is therefore easily affected by thermal stress during heat bending, resulting in cracking and damage.

[0007] The object of the present invention can be achieved by the following technical scheme: a curved tempered glass forming device, comprising a workbench, a working cavity is opened inside the workbench, a forming tool for hot bending tempered glass is fixedly arranged in the middle of the inner wall of the working cavity, the forming tool is the existing technology, and a heat preservation mechanism for heating the edge of the tempered glass is arranged on the back of the forming tool, and a cooling mechanism for quickly cooling the tempered glass is arranged on one side of the forming tool;

[0008] The cooling mechanism includes a water storage tank fixedly connected to the forming tooling, the bottom of the water storage tank is connected to a water outlet pipe, the bottom of the water outlet pipe is connected to a nozzle, the back of the water outlet pipe is connected to a water spray pipe, the output end of the water spray pipe passes through the workbench and is connected to a U-shaped pipe, and both output ends of the U-shaped pipe face the bottom surface of the tempered glass.

[0009] A further technical improvement of the present invention is that a transmission rod is longitudinally arranged inside the water tank, a sealing plug is fixedly installed on the top of the transmission rod, and a piston is fixedly installed on the bottom of the transmission rod, the piston is slidably connected to the inner wall of the water outlet pipe, and a guide frame for guiding the transmission rod is fixedly installed on the inner wall of the water tank.

[0010] A further technical improvement of the present invention is that an air vent is provided on the top of the water tank, an electric push rod is fixedly installed on the top of the water tank on one side of the air vent through a connecting seat, the extended end of the electric push rod movably passes through the air vent and is fixedly connected to the top end of the transmission rod.

[0011] A further technical improvement of the present invention is that an S-shaped heat exchange tube is fixedly arranged in the water tank on one side of the transmission rod, the input end of the S-shaped heat exchange tube is connected to a connecting tube, and the input end of the connecting tube passes through the water tank.

[0012] A further technical improvement of the present invention is that: a positioning plate is fixedly installed on the top back of the workbench, a fan is fixedly installed in the middle of the positioning plate, and the output end of the fan faces directly above the two output ends of the U-shaped tube; by closing the control valve and opening the fan, when the high-pressure airflow blown out by the fan performs preliminary air cooling on the molded tempered glass, the self-explosion caused by excessive cooling is prevented, and the hot air flow is injected into the S-shaped heat exchange tube, and the heat is transferred to the clean water in the water storage tank through the S-shaped heat exchange tube to obtain hot water, and the extended end of the electric push rod is controlled When it shrinks to its shortest, the sealing plug blocks the air hole. At this time, the piston is separated from the water outlet pipe. Since the sealing plug blocks the air hole, the air pressure in the water storage tank is increased, so that the hot water in the water outlet pipe is not only sprayed out through the nozzle, but also sprayed out through the two output ends of the U-shaped tube along the water spray pipe to cool the formed tempered glass. The high-pressure airflow blown out by the fan will blow off the moisture accumulated on its surface to prevent uneven distribution of moisture remaining on the surface of the tempered glass, which may easily lead to uneven shrinkage of the tempered glass and affect the product quality of curved tempered glass.

[0013] A further technical improvement of the present invention lies in that: the heat preservation mechanism comprises a support frame fixedly connected to the side wall of the forming tooling, a distribution pipe is fixedly installed on the front side of the support frame, two L-shaped tubes are fixedly connected to the bottom of the outer wall of the distribution pipe, and the output ends of the two L-shaped tubes are respectively facing the front and rear end surfaces of the tempered glass; the outer wall of the distribution pipe between the two L-shaped tubes is connected to a hot air pipe, the hot air pipe is inclined, and the output end of the hot air pipe faces one end of the tempered glass close to the positioning plate.

[0014] A further technical improvement of the present invention is that a pump body is arranged on the back of the molding tool, the input end of the pump body is connected to an air inlet pipe, and the output end of the pump body is connected to an air blowing pipe, and the output end of the air blowing pipe passes through the support frame and is connected to the end of the distribution pipe.

[0015] A further technical improvement of the present invention is that: the middle part of the blowing pipe is connected to the input end of the connecting pipe, and a control valve is fixedly installed at the end of the blowing pipe close to the distribution pipe, and a one-way valve is fixedly installed at the middle part of the connecting pipe, and the opening direction of the one-way valve is the same as the direction of the airflow in the blowing pipe entering the water tank; by opening the pump body and the control valve, the heat in the heating tooling is injected into the distribution pipe through the blowing pipe, and then the three edges of the tempered glass are heated and insulated by two L-shaped pipes and the hot air pipe, and the heat leaked from the opening of the heating tooling is used to insulate the end of the tempered glass away from the water tank, so as to avoid the rapid cooling speed at the edge of the tempered glass and prevent it from being easily affected by thermal stress and causing cracking and damage during hot bending.

[0016] A forming process for curved tempered glass, the forming process specifically comprising the following steps:

[0017] Step 1: The tempered glass entering the heating tool is heated to a point close to the softening point, and then the transmission roller is controlled to transport it to the processing station of the forming tool. Before the heated tempered glass is formed, the pump body and the control valve are opened to allow the heat in the heating tool to be injected into the distribution pipe through the blowing pipe, and then the three edges of the tempered glass are heated and insulated by two L-shaped pipes and hot air pipes. The heat leaked from the opening of the heating tool is used to insulate the end of the tempered glass away from the water tank, so as to avoid the edge of the tempered glass from cooling down quickly and prevent it from being easily affected by thermal stress during hot bending and causing breakage and damage;

[0018] Step 2: After the tempered glass is hot-bent, it is transported to the front of the positioning plate through the transmission roller, the control valve is closed and the fan is turned on. When the high-pressure airflow blown out by the fan performs preliminary air cooling on the formed tempered glass, it is prevented from self-explosion due to excessive cooling. After the hot airflow pushes open the one-way valve, it is injected into the S-shaped heat exchange tube through the connecting pipe, and the heat is transferred to the clean water in the water storage tank through the S-shaped heat exchange tube to obtain hot water. At this time, the discharged airflow passes through the air vent;

[0019] Step three: Then control the extended end of the electric push rod to shrink from the longest to the shortest, so that the sealing plug blocks the air vent. At this time, the piston is separated from the water outlet pipe, so that the hot water in the water tank enters the water outlet pipe. Since the sealing plug blocks the air vent, the air pressure in the water tank is increased, so that the hot water in the water outlet pipe is not only sprayed out through the nozzle, but also sprayed out through the two output ends of the U-shaped tube along the water spray pipe to cool the formed tempered glass; the atomized water sprayed from the nozzle will cover the top surface of the formed tempered glass, and the water flow sprayed from the two output ends of the U-shaped tube will cover the bottom surface of the formed tempered glass. The high-pressure airflow blown out by the fan will blow off the moisture accumulated on its surface to prevent uneven distribution of moisture remaining on the surface of the tempered glass, which is easy to cause uneven shrinkage of the tempered glass and affect the product quality of curved tempered glass.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When the present invention is in use, by closing the control valve and opening the fan, when the high-pressure airflow blown by the fan performs preliminary air cooling on the formed tempered glass, self-explosion due to excessive cooling is prevented, and the hot air flow is injected into the S-shaped heat exchange tube, and the heat is transferred to the clean water in the water storage tank through the S-shaped heat exchange tube to obtain hot water, and the extended end of the electric push rod is controlled to shrink to the shortest, and the sealing plug blocks the air hole. At this time, the piston is separated from the water outlet pipe. Since the sealing plug blocks the air hole, the air pressure in the water storage tank is increased, so that the hot water in the water outlet pipe is not only sprayed out through the nozzle, but also sprayed out through the two output ends of the U-shaped tube along the water spray pipe, so as to cool the formed tempered glass, and the high-pressure airflow blown by the fan blows off the moisture accumulated on the surface of the tempered glass, so as to prevent uneven distribution of moisture remaining on the surface of the tempered glass, which is easy to cause uneven shrinkage of the tempered glass and affect the product quality of the curved tempered glass.

[0022] When the present invention is in use, the pump body and the control valve are opened so that the heat in the heating tooling is injected into the distribution pipe through the blowing pipe, and then the three edges of the tempered glass are heated and insulated through the two L-shaped pipes and the hot air pipe. The heat leaked from the opening of the heating tooling is used to insulate the end of the tempered glass away from the water tank, thereby avoiding a rapid cooling speed at the edge of the tempered glass and preventing it from being easily affected by thermal stress during hot bending and causing cracking and damage.

Since the sealing plug (212) blocks the air vent (214), the air pressure in the water storage tank (202) is increased, so that the hot water in the water outlet pipe (204) is not only sprayed out through the nozzle (209), but also sprayed out along the water spray pipe (205) through the two output ends of the U-shaped tube (207), so as to cool the formed tempered glass; the high-pressure airflow blown out by the fan (208) blows off the moisture accumulated on its surface.
